Learn how to get the most out of Arandu.
On first launch, Arandu offers to install the arandu CLI automatically. You can also install it later via Arandu → Install Command Line Tool… in the menu bar, or install via Homebrew:
brew install --cask devitools/arandu/arandu
arandu README.md # open a file arandu doc1.md doc2.md # open multiple files arandu *.md # open all .md files in current directory arandu # open the file picker
If Arandu is already running, files open instantly via IPC. Otherwise the app launches automatically.
Go to Settings → Voice to Text and download a Whisper model. Transcription runs entirely on your device — no internet connection or API key required.
Press the global shortcut (configurable in Settings) to open the floating recording window. Speak your text, then click to stop — the transcription is copied to your clipboard automatically. You can also configure the audio input device in Settings.
Open a workspace directory, then click Connect to start a session. Arandu communicates with coding agents (such as GitHub Copilot CLI) via the Agent Communication Protocol (ACP) over stdin/stdout.
Switch to plan mode to generate a plan document. Review it inline with block comments, then move to the executing phase — all tracked per session within your workspace directory.
